He's close but he's not quite there yet. The scoring title this year boosted his resume and if the Knicks get to the ECF and upset the Heat he'll definitely be top 50. If they win the title and he gets FMVP he'll be top 35ish, maybe even higher because that would mean he likely beat 7 HOFers to do it.

i agree, and the title most likely will give him a finals mvp award, which makes him a top 20 (or even higher) player undoubtedly to me.

You are aware how elite top 20 is, aren't you? I mean not even Garnett and Dirk are consensus top 20 players all-time and, at their peak and in their prime, both were better than Carmelo's ever been, and both have rings. You can say Garnett wasn't "the man" on that 2008 Celtics team, but he was their best player.
